Sciophila Meigen, 1818 from the Orientai region (Diptera, Mycetophilidae). -Tijdschrift voor Entomologie 138: 283-289, figs. 1-11 [ISSN 0040-7496]. Published 15 November 1995. Sciophila bilobata sp. n., S.fistulata sp. n. and S. suthepensis sp. n. are described and male gen-italia are illustrated; for S. suthepensis also the female. These species are the first three confirmed species oi Sciophila from the Oriental region. It is pointed out that the only species previously recorded from this region, 5. bicolor Brunetti, 1912, should be considered a nomen dubium. Some tentative remarks are made about the systematical position of the new species. Geir E. E. Soli, Museum of Zoology, University of Bergen, Muséplass 3, N-5007 Bergen, Norway. Key words. -Diptera, Mycetophilidae, Sciophila, new species, Thailand. During an expedition arranged by the Museum of Zoology, University of Bergen, to the montane ever-green forests in Northern Thailand in April 1991, more than 1000 specimens of Mycetophilidae (s. str.) were collected. Among others the material held five specimens belonging to the genus Sciophila Meigen, 1818, representing three species, all of which proved to be undescribed. Species of the genus Sciophila can be identified in having their wing membrane densely clothed by large, decumbent trichia, a very short median fork, and a cu-bital fork branching out very close to the wing margin. A small, closed cell is present between Rs and R2,3. These two veins may, however, occasionally fuse. Altogether 113 species belonging to this genus are recognized, of which 48 are Nearctic, 34 Palaearctic (including 2 species from the Canary Island and 5 species from Nepal), 8 Holarctic, 2 Afrotropical, 1 Oriental and 20 Neotropical. The number of Neotropical species is, however, uncertain as more than half of the species may belong to other genera (Papavero 1978). One Australasian species, Austrosciophila solitaria (Tonnoir, 1929) from Tasmania, was originally described as a subgenus of Sciophila, but the subgenus has later been raised to ge-neric rank (Matile 1989). The single Oriental species, 5. bicolor Brunetti, 1912, is described from Darjiling, India (Brunetti 1912) based on 4 females. The species is not com-mented on by Edwards (1924) in his review of Brunetti's types of Mycetophilidae. Neither, has it been possible to trace the type specimens, and they are probably lost. Consequently, 5. bicolor should be regarded a nomen dubium. The world fauna of Sciophila has not been revised. but the Holarctic species, which constitute the great-er part of the genus, are treated by Zaitzev (1982). Methods and terminology All specimens were cleared and slide mounted in Canada balsam. The general terminology follows Vockeroth (1981) and McAlpine (1981), except for the clypeus and the female genitalia. Clypeus is here regarded as being secondarily divided in Mycetophilidae, consisting of an upper postclypeus and a lower anteclypeus (see al-so Matile 1990). The interpretation of the female genitalia is mainly in accordance with Ssether (1977), and will be further dealt with in a forthcoming paper. Cubital ratios are given as the length of CuA, and CilA;,, respectively, to the length of CuA-petiole. Two ratios are given for the fore, mid and hind leg each: the length of femur to tibia, and the length of tibia to first tarsomere. The lengths of the tibial spurs are given in relation to the tibial diameter, measured apically. Sciophila bilobata sp. n.
